One shot forming's halbach array permanent magnetism axial ring

The utility model discloses an one shot forming's halbach array permanent magnetism axial ring, including whole fashioned ring magnets, ring magnets cuts open along the axial and forms the face back of expansion and observe, along the magnetic field direction of the at least ring magnets of axial subregion in the face of expansion according to halbach array orientation, ring magnets's the oriented reinforcing magnetic field that forms of halbach array is at the ring magnets tip. The utility model discloses an axial ring forms through the one shot forming sintering, need not loaded down with trivial details assembly process, and production is convenient, stable in structure, and the magnetic field stability is good, and the range of application is wide, the facilitate promotion.
